A pube flambe is the outcome of a lit fart gone horribly wrong. This is more likely for those who have more ass hair. When a pube flambe occurs, the ass hair catches on fire and eventually spreads up the gooch to the chode. This is incredibly painful. Pube flambes are popular among people dumb enough to pull down their pants, then light one.
Joey was related to the Geico caveman, and decided to light one with his pants pulled down. Now he in the hospital with third degree burns. Why, you ask? It was the dreaded pube flambe...
Don't light farts with your pants pulled down, or this will eventually happen to you.
